Title: Reflecting mirror
Inventor: SUZUKI JUNTARO
IPC: G02B5/08
Filed: 1991-02-07
Abstract: PURPOSE:To prevent the mirror surface of the reflecting mirror from becoming cloudy by arranging a heat accumulation pack on the reverse surface side of the mirror surface part of a mirror body and arranging plural heat accumulation packs on the reverse surface of the mirror surface of the mirror body while the entire area is covered. CONSTITUTION:The heat accumulation pack 5 consisting of a container 3 which is flexible, a shape holding member 6 which is arranged in the container 3 and impregnable, and a heat accumulating material 4 with which the shape holding member 6 is impregnated is arranged on the reverse surface side of the mirror surface part 2 of the mirror body 1. When outside air temperature is lower than the fusion point of the heat accumulating material 4, the heat accumulating material changes in phase from liquid to solid to discharges latent heat. Further, the mirror surface part 2 of the mirror body 1 is much higher in heat conductivity than the heat accumulating material 4, so the temperature of the mirror surface part 2 of the mirror body 1 never becomes lower than the outside air temperature.

In this case, when the slump of a concrete kneaded matter is 5.0cm or less, the content of athapalgite is set to be 1.0kg/m<3> . When the slump is 5.0-8.0cm, the content of the athapalgite is 3.0kg/m<3> or more. When the slump is 8.0-13.0cm, the content of the athapalgite is 4.0kg/m<3> . The upper limit value of the content of the athapalgite in the concrete kneaded matter in the respective slump ranges is set to be 15kg/m<3> in consideration of the influence of strength. Accordingly, no white wash develops and, at the same time, a high strength is revealed in the article.

Abstract: PURPOSE:To enable the prevention of moisture condensation easily even during a humid time, by detecting optically moisture condensation on the wall face of an ozonizer, controlling automatically the amount of cooling water by a regulating valve for cooling water. CONSTITUTION:The feed pipe 11 for cooling water is equipped with the requlating valve 13 on the way to the main body container 1 of the ozonizer. When moisture condensation is observed by the detector 15 for finding the moisture condensation on the wall face at the outside of the main body container 1 of the ozonizer, the detected value g from the detector 15 is sent to the device 14 for regulating the valve, the opening and closing degree of the regulating valve 13 for cooling water is controlled by the output signal h from the device 14 for regulating the valve to prevent moisture condensation. Since the ozonizer 1 is a heating element, the temperature of the wall face of the main body container 1 can be changed easily by controlling the cooling water. Since cloudiness disappears with the rise in the temperature of the wall face, the cooling water may be made to flow at this point of time. The measurements of atmospheric temperature, cooling temperature, atmospheric relative humidity, etc. and the correspondence among them are not required, a control device by these values is not needed, so that moisture condensation can be prevented economically and inexpensively.
